Goudeau, 32, and musical partner Ashley Renée Watkins, 29, will be singing for America’s vote Tuesday night in the hopes of spreading opera to a larger audience and winning $1 million.

“People feel [opera] is not accessible and not familiar to them,” Goudeau said. “We kind of want to be ambassadors for the art form.”

The singing duo, Acte II, is one of 48 acts that made it to the season nine “America’s Got Talent” quarterfinals, where they get to appear live at Radio City Music Hall and compete for viewers’ votes.

The ladies received yeses from all four judges, Howard Stern, Heidi Klum, Mel B and Howie Mandel, in the NBC show’s season nine premiere on May 27. They were so impressed that Acte II was selected to go straight through to the live performances, bypassing a second audition in front of the judges.

Before making it to the reality show stage, Goudeau’s love for singing started in church and with gospel music. As she grew older, she was introduced to classical music. But her focus on singing and opera as a career came in college.

After switching from a computer science major to music, she thought her program would focus on jazz music, since she was attending Dillard University in New Orleans. But to her surprise, she learned the classics and her passion for opera was born.

It was also at Dillard that she met Watkins, but they didn’t become friends until Goudeau was working on her master’s degree at the University of Oklahoma and Watkins was one of several Dillard students the school hosted following Hurricane Katrina.

They grew closer when they both were a part of Opera New Jersey one summer. The idea for Acte II started as way for them to find more singing opportunities in Europe and to do a concert tour.

“We enjoyed singing together,” Goudeau said. “So we were like, why don’t we make this official?”

The name and the group came to represent more.

“We wanted to make our own opportunities,” Goudeau said. “It’s like a second phase in life.”

The same weekend they were set to have their first concert, at the First AME Church: Bethel in Harlem, where Goudeau is currently an artist-in-residence, “America’s Got Talent” was holding auditions.

“We were so nervous that [the judges] wouldn’t accept opera,” she said. The pair both had their “afros out” and dressed like “everyday people.”

The judges not only accepted the art form, but were surprised by their voices.

“That was a moment and that was your moment,” Mel B said, adding that the performance made the hair on her arms stand up.

On Tuesday they will need to garner the same reaction from viewers. And Goudeau, who moved to Queens six years ago to pursue her New York City opera dreams, is asking the borough to vote for one of their own.

“[My family has] embraced Queens so much. I just feel so comfortable here. It’s such a community,” she said. “I hope Queens people vote.”
